That's all the hint I can provide.
Anyway, Jiang Yuan couldn't directly tell him that these two skills can be merged using the system. If the old dragon can grasp the hint and figure out a skill to increase his lifespan, that would be a good thing.
Old Dragon: ???
I've comprehended and learned both sets of cultivation techniques. The ways of execution are completely different. Apart from both being "devour," how are they similar?
Despite racking his brains, he couldn't understand, but the other person's expression didn't seem like he was just making things up. Besides, since getting to know Jiang Yuan, he's been quite reliable and wouldn't say things without basis.
Could there be something within them that's worth pondering and comprehending that I haven't discovered yet?
"Thank you for your guidance, young friend." The old dragon thanked with a solemn bow.
